Explanatory Note

This Equivalency Certificate authorizes the transportation of anhydrous hydrogen fluoride (UN1052) in pressure tank cars with the following characteristics that are different from the requirements of clauses 8.2.6.1 and 10.5.1.1 b. of the Transport Canada Standard TP14877:

1) The tank cars are not equipped with external jackets as is currently prescribed for products with significant inhalation hazards. This continues an existing long time practice for tank cars in this particular service in order to allow for the easy detection of hydrogen "blisters" on the external surface of the tank when they occur.

2) The tank cars are equipped with safety relief valves that have a lower flow capacity than required by current regulations; the Applicant has demonstrated that the survivability of these cars in a pool fire situation is well in excess of the required 100 minutes. This is equivalent to other tank cars with larger safety valves in other dangerous goods service. The rationale is that, in situations requiring incident mitigation, a larger pressure relief valve could result in more material being released, which would be detrimental to the safety of the public, company employees and emergency responders.
